Aqua Worx Orion LED lights provide a high-performance and incredibly sleek solution for illuminating modern planted aquariums. Featuring clear, adjustable acrylic legs, these low-profile aquarium LEDs mount securely above your tank and blend seamlessly into your room's decor. The crisp, powerful white spectrum is specifically tuned to make the green hues in your aquascape pop with high-definition clarity. By optimizing light distribution across its compact frame, the Orion 18" ensures that the vivid coloration of your freshwater fish and aquatic plants can be fully viewed and appreciated.
This aquatic plant LED light has high PAR values and is well-suited for high-tech tanks with CO2 and fast-growing plants that require high light levels. When used on low-tech tanks, we recommend using a dimmer to prevent algae growth.
Choosing the right intensity is key to a healthy tank. Check out our guide on Lighting Requirements for a Planted Aquarium to see how to pair this light with your plant choice!

Good light
"I like the clear acrylic look on the legs. Light is nice and bright, but wish it had a blue light option and a dimming option."
Good light but lacking features of cheaper lights.
"I bought this light to replace a cheap $25 aquarium light I purchased off of Amazon. As I'm getting further into the aquascaping hobby I felt a light upgrade was due even though I wasn't unhappy with my cheap light. I think the light has a nice design aesthetic and seems to be well built. The light produces a strong and bright beam. That being said, I realized very quickly that the cheap Amazon light's 24 hour timer with integrated sunrise/sunset feature and dimmer functions were things I couldn't live without in the morning and evenings. I also needed to purchase an external power timer for my outlet to control the light on a schedule. For a light that costs as much as this one I'm surprised that it doesn't have any of those features. I've already replaced the light with a Chihiros due to the bluetooth connectivity and app control that allows for total customization of the timer and beam. I'm going to put this light into storage and save it for a future tank that will be setup in a living space that I don't use during morning and evenings where a 24 hour sunrise/sunset feature isn't necessary.."
Extremely powerful light at a great price.
"Extremely powerful light at a great price. I’d give it five stars, but it is hard to get an inline dimmer for (different size to Twinstar’s; out of stock at BP for quite a while now), and doesn’t come with any features, or even any instructions/documentation."
Great light for my new
"Great light for my new Vivarium!"
Very bright
"great light good quality build stays tight to the tank"
The look is very sleek
"The look is very sleek and cool. The metal rods are a little weird to work with, but not overly difficult. The light is very powerful and is great for my tank. Be careful of the power of the lights however because it can become hot to the touch."
Hot to the touch
"It’s hot to the touch after being run, but provides great lighting. Design defect would be two of the four bolts and nut caps dont screw on since the acrylic light stand is to thick for the nut to grab the screw threads. I’ve applied super glue so my light doesn’t fall into the tank when I’m maintenancing."
Great Light
"Love this light! Functional, stylish. What else is there"
I love this light
"As promised the light is very bright and brings out the colors in everything. Love the look of the legs acrylic and clean. It fit my rimmed 40b without any modification. Thanks buce y’all did it again!"
Excellent
"Visually very pleasing Simple , compact , very bright I’ve only had it 2 days but expect trouble free performance"
